Four decades of experience in developing and manufacturing coaxial and data line HEMP and LEMP protectors are the foundation of our EMP protector portfolio, and have made HUBER+SUHNER a first stop for protection solutions in defence applications.

H+S offers protection devices for land based, airborne and naval tactical communications as well as for navigation, radar and electronic warfare applications.

All protectors provide protection against direct and indirect interferences of lightning, but also HEMP. The products are designed to meet the stringent requirements of the defence and security markets and many of them are referenced by the NATO Maintenance and Supply Agency (NAMSA).

Self-extinguishing GDT protectors (Semper)

The HUBER+SUHNER Semper design guarantees safe extinguishing of the GDT under high RF power or with additional DC components on the antenna line.

Gas discharge tube protectors with exchangeable GDTs

For applications with RF and DC components on the antenna line, the standard GDT lightning / EMP protectors feature DC continuity and large bandwidth.

True broadband GDT protectors

SlimLine GDT protectors feature high return loss in the frequency band between DC and 6 GHz. This design is best suited for point to point and WLAN equipment.

Hybrid / low PIM / high power GDT protectors

This patented technology features low passive intermodulation at extremely high continuous and peak instantaneous power.

Bias-T / DC injectors with integrated lightning protector

Bias-T’s, used to ‘feed-in’ or ‘pick-off’ DC voltage into or from antenna feeder cables, provide the operating voltage for active electronics installed on the mast.

Quarter-wave shorting stub protectors

HUBER+SUHNER quarter-wave shorting stub protectors perform best lightning parameters with excellent RF specifications within limited bandwidth.
